Abstract
The utility model provides a follow -on steel protects a section of thick bamboo, includes barrel I, the columniform barrel II and the annular flat board of circle of round platform type, the macrostoma diameter of section of barrel I equals with the diameter of section of columniform barrel II, dull and stereotyped small circle diameter of section equals with the diameter of section of columniform barrel II, the open end of barrel II and the macrostoma of barrel I end pore free welded, dull and stereotyped suit is gone up and the seam crossing of welding at barrel II and barrel I at barrel I. Compared with the prior art, the utility model discloses set up the annular flat board of circle, this flat board can prevent that whole barrel from sinking, has played the effect of protection, simultaneously, change the outside shape that original steel protected a section of thick bamboo, improved the pile foundation construction straightness that hangs down, guarantee that the steel protects a section of thick bamboo and is higher than ground 200 all the time simultaneously 300mm, and the comparatively easy steel of extracting protects a section of thick bamboo after the pile foundation construction completion.
Description
Technical field
This utility model relates to a kind of steel pile casting, the steel pile casting of a kind of improvement, belongs to building and building pile foundation engineering technical field.
Background technology
Steel pile casting is during pile foundation construction, prevents from, owing to the factors such as soil property instability use the casing of steel to protect hole stake, preventing collapse hole from avoiding affecting construction speed and safety.Circular two that steel pile casting diameter typically big than the diameter of hole stake 200-400mm iron sheet hoop becomes is all empty bucket, has stable hole wall and prevents the effects such as hole, isolation surface water, starter, spud pile position, protection operation original ground of collapsing.
Conventional stake casing majority is that cylindrical and upper and lower sectional dimension is consistent.In protecting tube embedding work progress, it is more difficult to control casing and be above the ground level the requirement of burying underground of 200-300mm, and during mechanical execution pile foundation, construction machinery easily touches steel pile casting and makes steel pile casting run-off the straight and then affect perpendicularity.Construction machinery touching steel pile casting is likely to result in sinking steel protecting canister, makes steel pile casting end face flush even below ground with ground, brings potential safety hazard.There is bigger absorption affinity around when some weak soils and the compactness layer of sand area complete steel pile casting of pile foundation construction are extracted so that steel pile casting extract that speed is the most difficult very slowly extracts.
Summary of the invention
According to the deficiencies in the prior art, this utility model provides the steel pile casting of a kind of improvement, while improving pile foundation perpendicularity, it is ensured that steel pile casting is consistently higher than ground 200-300mm, and pile foundation construction complete after be relatively easy to extract steel pile casting.
This utility model is realized by techniques below scheme:
A kind of follow-on steel pile casting, cylinder I including circular platform type, cylindrical cylinder II and the flat board of annular, the big mouth diameter of section of described cylinder I is equal with the diameter of section of cylindrical cylinder II, and the roundlet diameter of section of described flat board is equal with the diameter of section of cylindrical cylinder II；The opening of described cylinder II and the big opening end seamless welding of cylinder I, described flat board is sleeved on cylinder I and is welded on the seam crossing of cylinder II and cylinder I.
Preferably, the height of described cylinder II is 200mm～300mm.
Preferably, the osculum diameter of section of described cylinder I 100mm～200mm bigger than construction stake diameter of section.
Preferably, big mouth diameter of section 200mm～400mm bigger than construction stake diameter of section of described cylinder I.
Preferably, the great circle diameter of section of described flat board is than big 200mm～500mm of osculum diameter of section of cylinder I.
This utility model beneficial effect:
Compared with prior art, this utility model is additionally arranged the flat board of annular, and this flat board is prevented from whole cylinder, serves the effect of protection；Meanwhile, change the external shape of original steel pile casting, improve pile foundation construction perpendicularity, can guarantee that steel pile casting is consistently higher than ground 200-300mm simultaneously, and pile foundation construction complete after be relatively easy to extract steel pile casting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
In figure: 1, cylinder I, 2, cylinder II, 3, flat board.
Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, this utility model is further described.
As shown in body 1, Fig. 2, a kind of follow-on steel pile casting, cylinder I 1 including circular platform type, cylindrical cylinder II 2 and the flat board 3 of annular, the big mouth diameter of section of cylinder I 1 is equal with the diameter of section of cylindrical cylinder II 2, and the roundlet diameter of section of flat board 3 is equal with the diameter of section of cylindrical cylinder II 2；The opening of cylinder II 2 and the big opening end seamless welding of cylinder I 1, flat board 3 is sleeved on cylinder I 1 and is welded on the seam crossing of cylinder II 2 and cylinder I 1；The height of cylinder II 2 is 200mm～300mm, it is ensured that shield-tube embedment height is above the ground level the requirement of 200-300mm；Osculum diameter of section 100mm～200mm bigger than construction stake diameter of section of cylinder I 1, big mouth diameter of section 200mm～400mm bigger than construction stake diameter of section of cylinder I 1, it is ensured that the perpendicularity of construction, it is more convenient that hole pile driving construction pulls out casing after completing；The great circle diameter of section of flat board 3 is than big 200mm～500mm of osculum diameter of section of cylinder I 1.
I 1 big mouthfuls of diameter of sections of cylinder are equal with cylinder II 2 diameter of section, and cylinder II 2 part is positioned at more than ground, and cylinder flat board 3 partial cross section is positioned at level ground, and in work progress, steel pile casting does not glances off and settles.
As the preferred mode of this utility model, steel pile casting below ground is that big upper and lower small mouth both ends open iron sheet hoop system forms, and reduces frictional force, conveniently extract compared with routine assistance body in withdrawal process.
This utility model changes conventional below ground cylindrical steel casing into class tapered steel casing, it is ensured that while perpendicularity, in steel pile casting extracts work progress, substantially reduces frictional force, can be relatively easy to extract；This utility model is additionally arranged the flat board 3 of annular simultaneously, and when this anti-sinking horizontal steel plate is fully contacted with level ground, steel pile casting no longer sinks and tilts, and improves construction precision；It is simple that this utility model has population structure, it is ensured that the security performance of structure, is drawn out easily, construction precision height, the not advantage such as free settling and inclination.
